How can I launch Jupyter Notebook in Safari?

Question

I am on a Mac OS, and my default browser is Firefox.

In terminal, I ran jupyter notebook --generate-config. Then, in a text editor, I opened ~/.jupyter/jupyter_notebook_config.py

I changed c.NotebookApp.browser = u'' to c.NotebookApp.browser = u'/Applications/Safari.app/Contents/MacOS/Safari %s'

However, when I run jupyter notebook, I get the following output:

```

```

Without the changes to the config file, jupyter launches okay in Firefox.

You almost had all steps. Re-iterating for the benefit of the readers.

Make sure that firefox is the default browser. Or any other browser for that matter.

I am using atom as text editor. Feel free to use any other.

Execute

$ jupyter notebook --generate-config
$ atom ~/.jupyter/jupyter_notebook_config.py

find and change

c.NotebookApp.browser = u''

to

c.NotebookApp.browser = u'/usr/bin/open -a Safari %s'

Test

$ jupyter notebook
